What Can A 40 Watt Laser Cut

Is the chinese k40 laser engraving machine and its 40 watt co2 laser tube powerfull enough to penetrate metal surfaces. In this episode i give a lightning fast overview of 40 different laser cutter projects grouped and organized by difficulty and the lessons they teach. There are a whole host of materials that a co2 laser cutter can cut etch or mark but some due to the material surface reflection just won t work aluminum is an example.

I had my co2 laser cutter for a couple of weeks now and in case you missed it i ve written up my initial experience with it over a three part article part 1 part 2 part 3.

What can a 40 watt laser cut.

A 5w laser cutter can cut through many materials that are up to 4mm 1 6 thick but are primarily used for etching. While other materials can be extremely hazardous to either humans or the machine itself like pvc and abs. 1 you can run your 60 watt laser with your 40 watt supply if you keep the current 16ma 2 although at 16ma you will not reach 60 watts you will achieve a marked increase over what you had before at the same current. Mike klos laser mechanisms converting to millimeters that s 1550 watts mm 2.

These are my findings. 3 you can reach 60 watts if you run the supply at full capacity 22ma but this will likely reduce its life. 1in 2 645mm 2 a 100 watt laser can achieve a power density of 1550 watts mm 2 in a spot size that is 0 6452mm 2 a spot size that is 0 6452mm 2 has a diameter of of 28mm or 280 micron using area pi d 2 2 280 micron. I will put it to the test and try to.

If stainless steel is to be clean cut using high pressure nitrogen assist gas see applications section for details regarding clean cutting and oxygen cutting a high power 500 watt machine. This is due to the reflectivity of the materials. If you are a hobbyist or professional who builds miniatures dollhouse furniture architectural models polishing off 3d printed models custom etched and similar items then a 5w laser cutter will be perfect for your needs. There is no single manufacturer or official design spec for these and they are all slightly different but work on the same or at least very similar principles a blue sheet metal box containing an allegedly 40 watt laser but usually closer to 30 watts using roughly similar controls some are analogue some are digital and with roughly.

Sheet metal cutting requires a power density of 10 6 watts in 2 source. When cutting aluminum or brass a 500 watt average power with 1500 watt peak power machine is required. Learn how laser cutters can cut wood easily and quickly. Wood is great for many projects but hand cutting is difficult and time consuming.

I ve had a bit of spare time to play around with it a little more did some cutting and engraving on various materials and at various settings.
